Two groups of five vehicles each running on diesel and petrol respectively, produce 6.4 kg and 5 kg emissions per day. Given the population standard deviation 4 and t0.05 = 2·306, test whether emissions of diesel and petrol vehicles differ significantly?
1
t calculated value < 2.306, thus emissions do not differ significantly.
2
t calculated value = 2·306, thus they produce equal emissions.
3
t calculated value > 2.306, thus emissions do not differ significantly.
4
t calculated value = 2.306, thus emissions differ significantly.
